Another option of course is initializing a new double that will take the value of n before the while loop, in case changing the input of the function is not an option.

If N != (N&-N): print yes
Else no

—————————————————–
n = int(input())
state = “YES”

while n > 1:
n = n / 2
if n % 2 != 0 and n != 1:
state = “NO”
else:
state = “YES”
print(state)

Wrong Code.- The operator ! is undefined for the argument type(s) int
